It took the race car 22 minutes to travel 114.4 kilometers. At what rate did the car travel? Use the formula r = StartFraction d Over t EndFraction, where r is the rate, d is the distance, and t is the time. Round your answer to the nearest tenth.

The rate of car travel is 5.2 kilometers per minute.

Step-by-step explanation:

We are given the following in the question:

Total time of travel = 22 minutes

Total distance covered = 114.4 kilometers

We have to find the rate at which the car is travelling.

Formula:

Rate, r

where d is the distance covered and t is the time.

Putting values, we get,

Thus, the rate of car travel is 5.2 kilometers per minute.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

55 degrees because 55+55=110 degrees
